Wild, experimental, outlandish and imaginative – Gehlhaar didn’t get the exposure he deserves

The music of Rolf Gehlhaar is not “pretty” – it’s pretty wild.

 You wouldn’t know from reading his name (nor from the fact that he was born in Breslau, Germany – now Wroclaw, Poland -, in 1943) – and I didn’t know until I checked his entry on Wikipedia for the sake of this review – that Gehlhaar is in an American composer. For the anecdote, his father was a kind of Werner von Braun, a German test pilot, aeronautical engineer and rocket scientist who ended up being recruited by the US Government. The Gehlhaars emigrated in the US in 1953 and Rolf took US citizenship in 1958, studying at Yale and Berkeley. 

But a seminal experience for him was when he became the personal assistant and member of the performing ensemble of Stockhausen in Cologne, in 1967, for four years. He became strongly involved in computer music, working at the major research centers in Europe including IRCAM in Paris and the major studios in Germany. In 1985 he designed the first version of a computer-controlled interactive software which he called “Sound-Space”, by which the audience can feedback on the music being played by moving around in a space, the movements being precisely detected by ultrasonic sensors. 

Solipse for amplified solo cello and tape delay from 1973, one of Gehlhaar’s earliest compositions, must quite simply be one of the most inventive pieces for solo cello from the second half of the 20th century, in the top drawer with Xenakis’ Kottos or Crumb’s Sonata (among those that spring immediately to mind). Like Xenakis, Gehlhaar doesn’t so much aim at melody as at sheer sounds. Nonetheless, there develops starting at 8:30 a long, quasi-drone passage, first in the softest caressing dynamics with the strings seemingly brushed by the bow, that borders on folk or repetitive music, of great beauty. The orchestral range of sounds and colors he elicits from a solo cello and the mirroring or echoing effects borne by the tape delay (the cello is pre-recorded) is simply stupendous. Cellist Julia Ryder is phenomenal.

Polymorph for bass clarinet and tape delay (1978) and Rondell for solo trombone with tape delay (1975) are architectured in a semi-aleatoric way following elaborate and disciplined principles of variation where the dominating influence of Stockhausen can be perceived, and, as with Solipse, the result is tonally fascinatingly lush and imaginative.

Diagonal Flying for piano and synthesizer is a later composition (1989) and also, at 30-minutes, the longest composition on disc. It applies the “Sound-Space” software to the gestures and movements of the performer, with electronic sounds entirely controlled by the pianist’s hand positions and movements and fed back. Again it develops a fascinating sound-world, where the piano rises to heights of frenzied pounding that I thought only Nancarrow’s mechanical piano could produce – kudos to Roger Woodward – interacting with eerie – and often humorous – electronic sounds, making the composition something like a duo for piano and electronic percussion. 

Based on this recording, I don’t understand why Gehlhaar is so badly represented on disc. Gehlhaar has a website and you can consult the catalog of his works and discography (the latter is not entirely easy to find: it’s counter-intuitive, but you need to click on the tab “Words”). His new works grind to a near stop after 1998, with nothing since 2006. His discography is also very short – this here is his only complete disc, the rest are tracks on compilation CDs. Solipse is apparently his most popular composition, with two other recordings. Available on the website is also a long presentation of Solipse (clicking on the link will open a Word document), the circumstances of its inception and its underlying concepts. Gehlhaar is currently Professor of Design and Visual Arts at the Coventry School of Art and Design in the UK, his “subject expertise” being sound/music, design, sensor electronics, interactive multi-media.

 So here is a case of a composer who obviously didn’t make it to the public prominence his compositions would have deserved. Why? Too experimental and wild, maybe.
